Guidance from genpd team is to use a different power domain for each
device to avoid race condition in genpd framework when multiple devices
on same power domain runtime suspend in parallel.

When all clients remove DDR bandwidth vote, DDR may power collapse.
As part of its shutdown sequence, it waits for an 'active' signal to
no longer be asserted by the gpu cx gdsc. Thus, if SW votes for the
gdsc to be active, but not for DDR bandwidth, this sequence may
get stuck.

ZRAM is being disabled on tuivm due to observed stability issues due to
ZRAM's use of GFP_MEMALLOC. Increase maximum movable zone size to
compensate.
When kswapd swaps out pages, PF_MEMALLOC is set, which results in zram
ignoring the min_watermark, and lowmem_reserve. This is problematic
because we intend for movable memory to stay in ZONE_MOVABLE, rather
than falling back to ZONE_NORMAL. If the later occurs to such a high
degree that all ZONE_NORMAL memory is consumed, as is observed to be
the case during a "C2PA" testcase, attempts to plug in additional
ZONE_MOVABLE memory may fail due to requiring a small amount of
GFP_KERNEL memory.

"qcom,initial-movable-zone-size" creates a movable zone of the given size
before userspace starts. This is useful in a system where a userspace
component (psi-daemon) is used to hotplug in memory on a on-demand basis.
With swap disabled, the current tvm carveout size (68 Mb) hits
out-of-memory condition before psi-deamon is started.
Once psi-daemon is running, it detects the number of blocks added to the
movable zone via "qti_virtio_mem/kernel_plugged" sysfs file, and
can reduce or increment the number as necessary.

The virtio-mem device has always had a dependency on mem-buf for plugging
in memory. Previously, the ordering was not a concern, since hotplug was
not done until userspace was up. However, in subsequent patches we
will instead hotplug in memory as soon as the virtio-mem device probes.
